In the United States, approximately 20% of patients hospitalized with pneumonia are readmitted to a hospital within 30 days. Given the significant costs and healthcare system use resulting from unplanned readmissions, pneumonia readmission rates are a target of national quality measures. Patient do-not-resuscitate (DNR) status strongly influences hospital pneumonia mortality measures; however, associations between DNR status and 30-day readmissions after pneumonia are unclear. ⋯ Patients with an early DNR order have a lower risk for readmission after a pneumonia hospitalization. Unmeasured DNR status weakly confounds hospital readmission measures; accounting for patient DNR status would alter readmission ratings for a small number of hospitals.

Adoption and de-adoption of adjuvant strategies to mechanical ventilation for acute respiratory failure (ARF), and factors associated with their selection, have not been extensively evaluated. ⋯ Between 2008 and 2013, there was an increase in use of ECMO and inhaled epoprostenol, and no change in use of inhaled nitric oxide or continuous intravenous infusion of a neuromuscular blocking agent. There was considerable variability in patient and hospital factors associated with use across different adjuvants.

A Laboratory-based Analysis of Nontuberculous Mycobacterial Lung Disease in Japan from 2012 to 2013.
Since 2010, mycobacterial examination results have been used widely to survey nontuberculous mycobacteria (NTM) lung disease. ⋯ This investigation is the first laboratory-based study in which a large number of NTM isolated from clinical samples in Japan have been assessed. Although the calculated prevalence of NTM disease might be underestimated, the approach may prove useful for monitoring relative epidemiological data for NTM lung disease.

Patients without a known history of lung disease presenting with a spontaneous pneumothorax are generally diagnosed as having primary spontaneous pneumothorax. However, occult diffuse cystic lung diseases such as Birt-Hogg-Dubé syndrome (BHD), lymphangioleiomyomatosis (LAM), and pulmonary Langerhans cell histiocytosis (PLCH) can also first present with a spontaneous pneumothorax, and their early identification by high-resolution computed tomographic (HRCT) chest imaging has implications for subsequent management. ⋯ HRCT image screening for BHD, LAM, and PLCH in patients with apparent primary spontaneous pneumothorax is cost effective. Clinicians should consider performing a screening HRCT in patients presenting with apparent primary spontaneous pneumothorax.

The optimal anticoagulation strategy for venovenous extracorporeal membrane oxygenation (VV-ECMO) is not known. ⋯ The role and optimal therapeutic targets for anticoagulation during VV-ECMO are unclear. Previously published studies are limited by retrospective, observational design, small cohorts, and patient heterogeneity. The clinical significance of reported thrombotic complications is largely unknown. This systematic review underscores the need for randomized controlled trials of anticoagulation strategies for patients undergoing VV-ECMO for respiratory failure.
